There are also a number of open casting calls that you can attend in person. The dates, locations and times of these can be found on the application pages. I've always wanted to apply for The Amazing Race or Survivor; maybe I'll do both. If you can't make one of the open casting calls (which is likely), then, to apply, you must make a short video of yourself and send it in to the producers.
I don't know what the key to making these videos is, or what exactly producers are looking for (it certainly helps if you're good-looking), because every season of every show is different. I'm guessing that The Amazing Race is a little easier to get onto than Survivor, if only for the mere fact that less people apply for The Amazing Race.
If recent seasons are any indication, if you're applying to be on Big Brother, you're going to need to be young and very attractive.
